The number of chips of different colors in amy's bag is shown below:

8 blue chips
9 pink chips
1 white chip
amy takes out a chip from the bag randomly without looking. she replaces the chip and then takes out another chip from the bag. what is the probability that amy takes out a pink chip in both draws?
9 over 18 multiplied by 8 over 17 equals 72 over 306
9 over 18 plus 8 over 17 equals 297 over 306
9 over 18 multiplied by 9 over 18 equals 81 over 324
9 over 18 plus 9 over 18 equals 18 over 18
